 Solution: Use Arduino Uno as ISP. Upload 'ArduinoISP' sketch from Arduino IDE.
 Connect SPI pins (ATmega328P ↔ Uno), Uno's SS pin → ATmega328P RESET pin. Power
 ATmega328P from Uno's 5V pin during programming.

 ## Remarks
 
-Don't connect AREF (pin 21) to V<sub>cc</sub> if using ADC with internal 1.1V
+Don't connect AREF (pin 21) to V<sub>cc</sub> if using ADC with internal 1.1 V
